Embodiment

Its " one " used in this, " one ", "the", " at least one " and " one or more " system is interchangeably used." and/ Or " second word means one of listed article, one or more, or all.The number range stated with end points circle includes all include Whole numbers in the range of this (such as 1 to 5 is to include 1,1.5,2,2.75,3,3.80,4,5 etc.).

Can be according to a tradition numbered in this schema, wherein the first numeral system corresponds to the figure number, and remaining is counted Word can show not one of figure component.Component as in different figures etc can be shown not with similar numeral.For example, 354 can The component " 54 " in the 3rd figure is indicated, and 454 can be denoted as in one of the 4th figure similar component.It is emphasized that this etc. The purpose of schema be will for example,

And at all no intention to being used as limitation.May not in scale in this schema, and the relation of the component in the grade figure It may be exaggerated.The schema such as this system is used to be illustrated in the conceptual configuration and method described in this.

Shipping container (being also known as counter, shipping container, many titles such as formula container and/or ISO container) can be by with iron Road, aviation, highway and/or water route are transported.Counter can be transported by unloaded often.Because the counter whether has loading goods Thing can all take identical volume, therefore the cost (finance and environmentally) for having transported counter can be equal to the fully loaded goods of transport one The cost of cabinet.For example, the lorry (such as 5) of same number will be needed to convey the empty counter (such as 5 of same number It is individual).In addition, counter often can be vacant at storage place and/or the hub of communication.No matter counter position (is wherein in fortune Send or deposit), the volume that an empty counter takes not is used to its whole potential.

It is a kind of to this problems such as solution be one can reverse folding counter, person as described in this.One can if having Tolerable " sky " counter is folded into by the counter of reverse folding can reach a volume smaller than its fully extended state.This The additional volume heir obtained by folding counter at least partially can be used to accommodate the counter of other foldings at least partially, and The volume increased can be provided for for not folding (such as conventional) counter and/or the folding goods in the fully extended state Cabinet.Thus, for example, many (such as 5) reversely the empty counter of folding can be folded and be stacked into and enable a lorry Convey the empty counter of the number.As a result the saving of the grade environment and expense can be expected to considerable.

Such as will more completely it be discussed in this, the engagement member of this exposure has purposes (such as goods for some works Cabinet, dismountable structure is for example used in the folding array of the solar panels of space flight, Gu seat wheelchair, and hydraulic crane etc.) It includes a beam, or number beam, is used as some of the structure.Such as it is used for this, a girder system refers to a structural component, it can hold By a load, main system can impedance flexure.The engagement member of this exposure can be configured to a beam, or a beam some, for For the grade works.But, in addition to an effect such as beam, the engagement member of this exposure also allows that the structure is folded.When In a folding state, the works can take a volume, and it is the volume in a non-folding state less than the works.Cause This, in folding state, the works can take a volume and/or area, its be less than the works in a non-folding state Person.

Another remarkable advantage system of the engagement member of this exposure is the maximum length that it can be defined in one of the engagement member Interior equivalent surprising ability (for example, the maximum length defined can be one of engagement member maximum length).With regard to different realities Apply for example, this maximum length defined of the engagement member can be the engagement member defining most in a non-folding state Long length.Therefore, the engagement member of this exposure can be transferred to a folding state by a non-folding state, without making the engagement structure Any part (such as engagement member can assist define the end of the maximum length defined) of part extends beyond it and defined Maximum length.The problem of engagement member that discussion below will be helpful to more to differentiate this exposure assists to overcome.

1A and 1B illustrate one according to one or more embodiments of this exposure can reverse folding type counter 100. This in 1A and 1B figures can reversely folding type counter 100 some part be removed (for example top board structure part, side wall construction portions Part, base arrangement part, end frame portion part, interior assembly part etc.), with the setting of the engagement member of allowing this exposures and position relatively Put, its be in the present embodiment effect as this reversely can traverse component by one of folding type counter 100, can be seen more clearly. Shown in 1A figures can folding type counter 100 be reversely to be illustrated to be in a non-folding state.

As shown in 1A figures, this reversely can include one first corner post 102-1, one second corner post by folding type counter 100 102-2, a third angle post 102-3, and a fourth angle post 102-4.In one or more embodiments, grade corner post 102-1 is extremely 102-4 systems are the vertical support for bearing load, and they are rigidity and not foldable.In addition, grade corner post 102-1 is extremely 102-4 systems have enough intensity and sustainable many be stacked can be reversely other completely full on folding type counter 100 at this The weight of the counter of load.In one or more embodiments, each corner post 102-1 to 102-4 all includes one jiao of assembly parts 104-1 extremely 104-8.The isogonism assembly parts 104-1 to 104-8 can be used to clasp, move, place and/or fix this can reverse folding type goods Cabinet 100.In one embodiment, the grade corner post 102-1 to 102-4 and angle assembly parts 104-1 to 104-8 can be according to for counters Iso standard, for example iso standard 688 and iso standard 1496 (and iso standard 1496 of amendment) etc..

This reversely can also include one first bottom side rail bar 106-1 and one second bottom side rail bar 106-2 by folding type counter 100. As indicated, first bottom side rail bar 106-1 systems are located between the first corner post 102-1 and the second corner post 102-2, and second bottom Siding track bar 106-2 systems are located between the third angle post 102-3 and fourth angle post 102-4.This reversely can more be wrapped folding type counter 100 Containing one first upside rail bar 108-1 and one second upside rail bar 108-2.First upside rail bar 108-1 can be located at this first Between corner post 102-1 and the second corner post 102-2.Second upside rail bar 108-2 can be located at the third angle post 102-3 and the 4th Between corner post 102-4.

This reversely can further include an engagement member 110 according to this exposure by folding type counter 100.As indicated, first He By two or more, the grade engagement member 110 is engaged for second bottom side rail bar 106-1 and 106-2 systems.In different embodiments, when The folding counter 100 is in a non-folding state, and the engagement member 110 is acted on as this can reverse it in folding type counter 100 One " traversing component ".Function such as one traverses component, and the engagement member 110, which can be acted on such as a beam, to be placed in this holding band one and can reversely roll over Structural load on one of stacked counter 100 floor panel structure thing.Thus, the engagement member 110 of this exposure can be such as ISO marks Defined assists to hold the structural load of band one in standard 1496.But, typically component, the engagement structure of this exposure are traversed unlike one Part 110 can then be used to assist this can reversely folding type counter 100 relative to being indulged in the grade with one of bottom side rail bar 106 and 108 To 114 and in horizontal 112 reversibly foldings.

Can folding type counter 100 be in reversely at least part folding state there is shown with this referring now to 1B figures.Such as 1B Shown in figure, this can the engagement member 110 of reverse folding type counter 100 fold into the volume 116 that is defined by the counter 100 In.When 110 folding of engagement member, the grade corner post 102-1 to 102-4 and angle assembly parts 104-1 to 104-8 can be by laterally It is dilatory to be close together.Again, this can reversely folding type counter 100 by a non-folding state (such as 1A figures) these The reduction of volume 116 and " footmark " (such as area), by can due to the presence of the grade engagement member 110, and at least partially by Reach.

Such as more completely discussed in this, a major obstacle overcome by the engagement member of this exposure is that its ability not only may be used In a non-folding state, effect such as one can support a load, and for example one of defined is loaded in iso standard 1496, Constructive elements or beam, and can also change in its surprising ability towards a folding state, without having the engagement member 110 Any part extend beyond its maximum length 119 defined defined in a non-folding state.The importance of this problem System is presented below as.

The 2nd figure is referred to, there is shown with the end view of a counter 218.The counter 218 is to be shown with a partial view Go out, the part of the wherein base arrangement (such as timber apron), side wall construction, end frame and door assembly has been removed, more preferably to show The problem of going out to attempt the folding counter 218 and can meet with.The counter 218 and the engagement member not comprising this exposure, but shown Hinge 220-1 to 220-3 etc. is provided, it can connect two parts (such as two halves) for traversing component 222.Traditional idea will It may require that the grade hinge 220-1 to 220-3 should be able to be acted on such as a bearing, it can not only traverse this two half-connections of component 222 Together and bottom side the rail bar 206-1 and 206-2 of the counter 218 are connected to, and can also allow that this traverses component 222 and folds into the goods In one of cabinet 218 volume 230.

This, which traverses component 222, can have a variety of cross sectional shapes.The prismatic shapes may include box-like (such as rectangle or side Shape), C conduits, Z-shaped beam, and I-beam cross sectional shape.As indicated, this prismatic shapes, which may be allowed this etc., traverses component 222 Surface 224 in non-folding state mutually tight against.When tight against when, the surface 224 that this etc. traverses component 222 can be compressed, when having When one structural load is placed on the bottom plate of the counter 218, it can prevent this from traversing component using hinge 220-1 help 222 upper surface 221 extends below a plane 226.The plane 226 is an imaginary flat surfaces, thereon a connection any two The straight line of point all can fully horizontal.Therefore, in the present embodiment, this traverses any 2 points on the upper surface 221 of component 222 all It can be flat in the plane 226.

As indicated, the setting of the grade hinge 220-1 to 220-3 seems to may be allowed the base arrangement of the counter 218 one most Define folding in width 229 greatly.However, really not so.Very big the problem of, can produce in 218 folding of counter.These problems System is sufficiently large that the structural integrity of the counter 218 may traverse component 222 at this and start to use hinge 220-1 to 220-3 Involved impaired etc. when carrying out folding.When impaired, the counter 218 may be no longer complies with iso standard.Moreover, the counter 218 can Can not also can support again load and/or be available in structure.

As indicated, the component 222 that traverses of the counter 218 is to define width 229 in non-folding state, and with a maximum. Also show three hinge 220-1 to 220-3 etc. in counter 218 again, they seem to may be allowed the counter 218 to traverse component 222 Folding is in the volume 230 that the counter 218 is defined.The relative position of three hinge 220-1 to 220-3 is inspected, is had always Each angle of angle triangle 232 (being shown with hacures) occurs.The right angled triangle 232 includes a hypotenuse 234, and it is more straight than this One of angle triangle 232 first pin 236 or a crus secunda 238 are longer.As understood, the length of the crus secunda 238 is more long then should Hypotenuse 234 can be longer.

Also it can be seen that, in non-folding state, the length of two first pin 236 can assist to define the counter 218 Maximum defines width.If now the counter 218 converts into by a non-folding state, the width of the counter 218 must become It must define that width 229 is bigger could to accommodate the length of the hypotenuse 234 than the maximum.Therefore, if this traverses component 222 along the operation side To 240 movements, then it will not be available for constitute two parts that this traverses component 222 by enough width for from the non-folding state It is mobile or be back to the state (such as the bottom plate system of the counter 218 situation parallel with the plane 226).This problem is to be claimed herein For " hypotenuse problem ".

At least one of if constituting two parts for traversing component 222 to be forced to move along the traffic direction 240, following May occur：(1) the whole width of the counter 218 must increase above its maximum and define width 229；(2) this is constituted to traverse Two parts of component 222 must bend or deform (flexibly or non-resiliently)；And/or (3) this first, second and/or Two hinge 220-1,220-2,220-3 will be deformed and/or be broken.This problems such as, can have a works 243 and the counter 218 Become apparent when being used together, for example a top board structure thing and/or a horizontal securing structure, it respectively all has one to fix length Degree and/or width and the maximum that or can not should not extend beyond the counter 218 defines width 229.These horizontal securing structures it Example may include, but be not limited to：Cable, structural beam, bar and/or pipe etc., they can be used to assist in a non-folding state Fasten and support the counter.As understood, (such as top board structure thing, one laterally fastens structure to these one or more works Part, one or more hinges, and/or this traverses component 222, and other structures thing etc.) may be in the counter 218 by a non-folding State is damaged when equivalent.

No matter what occurs, there is a thing to be almost inevitable, because described hypotenuse problem expands beyond the counter 218 Its maximum, which defines width 229, will cause the reduction of the counter 218 (hinge 220-1 to 220-3 such as this, this traverses component 222 and/or the works 243), and it is supported a load again, iso standard such as being no longer complies with this, therefore can make The counter 218 is not suitable for its predetermined purpose.Therefore, when one counter is transformed into a folding state by a non-folding state When, it is it is desirable that the width of the counter will not expand beyond it defines width 229 in the maximum of the non-folding state.

The engagement member of this exposure can overcome described hypotenuse problem.The engagement member, as take off and state, can assist to make a goods Cabinet, for example this can reverse folding type counter 100, a folding state can be transformed into by a non-folding state, without making the counter Maximum define width expansion more than the non-folding state.It is all these to be all achieved, without recessed curved engagement member also This, which will not be damaged, to be reversely pivotally connected thing (such as hinge) by one of folding type counter 100.

In addition, when a works 143 with this can reversely folding type counter 100 is used together when (such as top board structure a thing And/or a horizontal securing structure), the engagement member 100 may be allowed this can reversely folding type counter 100 the works 143 it Reversibly folding in one regular length and/or width.The example of the grade works 143 may include but be not limited to：It is cable, structural Beam, bar and/or pipe etc., it can be used to assist to fasten and support this can reverse folding type counter 100 in a non-folding state. Read this exposure will recognize that the grade works (such as top board structure thing, a horizontal securing structure, one or more hinges, And/or the engagement member 110, and other structures thing etc.) reversely folding type counter 100 can converted into by a non-folding state when this When will not be damaged.

As described, the length that the engagement member system is configured to hypotenuse when in folding process can change and (such as can be adjusted It is suitable) and can prevent from damaging the grade engagement member, associated hinge and works (such as 143).This can reverse folding type counter It can change back to the non-folding state by the folding state, therefore be for can reverse folding.

Referring now to the 3rd figure, wherein showing the engagement member 310 of this exposure with an exploded view.As indicated, the engagement member 310 include the one first elongation elongation section 344 of section 342 and 1 second.Respectively the first elongation section 342 and second extends section 344 can have an equal length.Or, the one of first elongated portion 342 or second elongation section 344 is than another elongation Section is longer.

In one or more embodiments, respectively the first elongation elongation of section 342 and second section 344 all has a length oval Hole 346.As described, an elongated hole, for example 346 and other in this person, can have the shape or a pair of D of a Long Circle Shape.Therefore, the oblong second word can be come with the word language such as " Long Circle " or " double D-shapeds " if necessary when being used for now Substitute.Long Circle system is defined as the semicircle institute makers-up connected by the parallel line of two end points for being tangential to them.Double D Shape system is defined as the arc institute makers-up connected by the parallel line of two end points for being tangential to them.If being used for this, One Long Circle or double D-shapeds are simultaneously circular not comprising one.

As indicated, there is the first elongation section 342 first surface 348 can define one through the first elongation section 342 the first elongated hole 350, and the second elongation section 344 there is a second surface 352 can define one second stretch through this Second elongated hole 354 of long section 344.As indicated, respectively the surface 348 and 352 all has (first length of a first end 355 Elliptical aperture is denoted as 355-A, and second elongated hole is denoted as 355-B), and (this first at one second end 357 Elongated hole is denoted as 357-A, and second elongated hole is denoted as 357-B), wherein second end 357 is Along one of each elongated hole 354 of first elongated hole 350 and second longitudinal axis 359 in contrast to the first end 355.

The engagement member 310 also fastens thing 356 comprising one, and its some can be through first and second elongated hole 350 and 354.After such as will being more completely discussed in, the fastening thing 356 may pass through the elliptical aperture of the first elliptical aperture 350 and second 354.The heir of fastening thing 356 can be locked in positioning to assist to hold the first elongation elongation of section 342 and second section 344 Together (such as fastening thing 356 can mechanically engage the first elongation elongation of section 342 and second section 344).

When the fastening thing 356 mechanically engages the first elongation elongation section 344 of section 342 and second, this first The elongation elongation of section 342 and second section 344 can also slide relative to one another and be rotated around the fastening thing 356.First elongation The ability that the elongation of section 342 and second section 344 can be slided relatively allows the length of the hypotenuse when the engagement member 310 converts into Change, and can prevent from damaging the engagement member, associated hinge and works etc., as previously described.This relative can slide and around The ability of the fastening thing 356 rotation, which can provide at least two features, can allow the engagement member 310 to be used for overcoming the hypotenuse problem.This After this concept of invention will be more completely discussed in.

The use of various fastening thing 356 is possible.For example, the fastening thing 356 can be the form of a bolt or rivet.
